From the product name, it seems that stainless steel will not rust, but it is not. We need to know the specific methods to avoid rust from stainless steel products. In fact, this has a lot to do with the nickel element in stainless steel solid round rods. The following and The editor of the same metal will look at a few key points to avoid stainless steel rusting, for your reference only.
1. In polluted air (such as an atmosphere containing a large amount of sulfide, carbon oxide, and nitrogen oxide), when it encounters condensed water, it will form sulfuric acid, nitric acid, and acetic acid liquid points, causing chemical corrosion.
2. Organic juices (such as vegetables, noodle soup, sputum, etc.) adhere to the surface of stainless steel screws. In the presence of water and oxygen, organic acids are formed, and organic acids will corrode the metal surface for a long time.
3. The attachment of dust or heterogeneous metal particles, in the humid air, the attachment and the condensed water of the stainless steel screw connect the two into a micro-battery, which triggers an electrochemical reaction and destroys the protective film, which is called electricity. chemical corrosion.
4. The surface of the stainless steel bar adheres to acid, alkali, and salt substances (such as alkaline water and lime water splashed on the wall for decoration), causing local corrosion.
